What Should I Consider When Buying a Computer Mouse?

Computer peripherals are the majority of hardware devices other than the host computer. They can be called external devices, or peripheral devices, for short. Computer systems without input and output devices are just as meaningless as computer systems without software.

The display is a

The mouse is the basic control input device for Windows and is easier to use than the keyboard. This is due to the graphic features of Windows that need to be specified with the mouse and moved and clicked on the screen. The shape of the mouse varies. ^[1]

Keyboard belongs to

In actual work, there may be a large number of drawings, photos and various charts, which need to be input into the computer for processing, but pictures, photos and other information cannot be directly input by keyboard and mouse. And mouse, that would be a very onerous job. therefore,

In our daily work, we often need to print out the documents and pictures we have done on the computer. This depends on the printer, so the printer is generally

The so-called digital camera is a special type that can shoot and convert the captured scene into an image stored in a digital format through internal processing.

Digital cameras are cameras

A CD burner looks no different from a regular CD drive, but it is much more powerful than a CD-ROM. Functionally speaking, burners are mainly divided into CD-R burners and CD-R / W burners. CD-R burners can burn CD-R discs, and CD-R / W burners can use CD-R / W discs in addition to CD-R discs. CD-R discs can only be written once (supports segment recording), and CD-R / W can be rewritten many times. Recently, major burner manufacturers have stopped producing CD-R burners and switched to CD-RW burners.

USB stick

A USB flash drive is called a USB flash drive, and it is also called a flash drive (title). It uses USB interface technology to work with the computer. The use method is very simple, just plug the USB disk into the computer's USB interface, and then install the driver (generally install the driver that comes with the purchase, if you don't have one, you can go to the Internet to download a universal USB driver

However, the general U disk version (including XP, 2003) above Windows 2000 system does not need to install the driver and the system automatically recognizes it, which is very convenient to use.

A floppy disk requires the computer to be equipped with a floppy disk drive (ie, a floppy drive).

The reading speed of the U disk is dozens to hundreds of times faster than the floppy disk. The minimum storage capacity of the U disk is 6MB (now the market is almost extinct), and the largest is GB. The capacity of the floppy disk is only 1.44MB. As far as the capacity is concerned, one is under the sky and the other is under the ground. The U disk is not easy to be damaged, and the floppy disk is very easy to be damaged, which is not convenient for long-term storage of data.

Maybe when the U disk appeared before, we could not do without the floppy disk for some problems, for example: the system crashed, the floppy disk was needed to boot the system, and the system was repaired, but the U disk did not have the boot function at that time, so at this point You can't do without a floppy disk.

But now many U disks support system boot, and the boot speed is faster than floppy disks, so now basically floppy disks are obsolete products.

Tip: After reading and writing to the USB flash drive, do not remove it directly (except for Windows 98), because the USB flash drive will write data to the cache when it is used above 98. If it is directly removed at this time, it may cause data loss. . The correct operation should be double-click the new hardware icon in the system tray area in the lower right corner, stop the device in the system (ie clear the cache, save the data), and then unplug it.
